Tiberian Dawn and Expansion Command & Conquer Gold: Project 1.06 by Nyerguds: http://nyerguds.arsaneus-design.com/cnc95upd/cc95p106/

Red Alert and Expansions Portable RA by Iran: http://iran.cnc-comm.com/ra/

Tiberian Sun and Expansion Tiberian Sun Client by Tiberian Sons: http://www.moddb.com/mods/tiberian-sun-client

These versions are acceptable since they have much better compatibility with newer operating systems and don't actually change the game play.

Red Alert 2 and Yuri's Revenge RA2/YR Client: https://cncnet.org/yuris-revenge#download While this client requires the full game to work and does not support the campaign, you can copy ddrawcompatTS.dll from Resources folder into your RA2/YR directory and rename it to "ddraw.dll" for a much better experience on newer operating systems.

Ultimate Collection C&C Ultimate Collection Launchers by Bibber: http://bibber.eu/downloads/cnc-ultimate-collection-launchers/ UI's for TW, KW, RA3, and Uprising are disabled by default. With this patch, you will be able to run an older version of the game.
